Certain specific electrochemical behaviour of some aldehydes. Potentiodynamic investigations
(Russian Journal of Electrochemistry, 1997)
Two distinct specific features have been clearly observed and recorded by cyclic voltammetry in alkaline aldehyde (typical simple aldehydes and monosaccharides) solutions: (a) Heterogeneous reaction of aldehyde group ...
Coupled vertical mast (monopole) antennas in the presence of a conducting half-space
(Ieee-Inst Electrical Electronics Engineers Inc, Piscataway, 1998)
The unknown current distribution (UCD), self and mutual admittances (impedances), grounding impedances of coupled vertical mast antennas (CVMA) on a conducting halfspace are presented in this paper. The UCD is determined ...
Separability degree of clusters based on the production results indicator / Stepen razdvajanja izdvojenih klastera na osnovu indikatora rezultata proizvodnje
(Univerzitet u Beogradu - Poljoprivredni fakultet, Beograd, 1999)
The business result of a family farm is a multidimensional criterion. There are, however, difficulties in determining homogenous subsets, considering the pace and movement trends of the indices of production results. The ...
The application of the electronic and the X-ray photoelectric spectroscopy (XPS) for the examination of the passivization film on the tinplate / Primena elektronske i fotoelektronske spektroskopije X-zracima (XPS) za ispitivanje sastava pasivizacionog filma na belom limu
(Univerzitet u Beogradu - Poljoprivredni fakultet, Beograd, 1999)
